zabbix is a monitoring solution, I am sure this sets up some kind of outgoing mail, but I was looking for a solution similar to iredmail.

Sorry, I'm mixing it up with Zimbra. Too many weird names.

I don't see an iredmail role, but having used Ansible previously, if you can install it chances are you can write an Ansible playbook for it.
